Question

Сомолет летит горизонтально со скоростью 800 км/ч. Вычислить разность потенциалов, возникающую между концами его крыльев, если вертикальная составляющая индукции магнитного поля Земли 40 мкТл, а размах крыльев 15м.

Answer 1

Сомолет летит горизонтально соСомолет летит горизонтально со скоростью  V=800 км/ч. Вычислить разность потенциалов, возникающую между концами его крыльев, если вертикальная составляющая индукции магнитного поля Земли B= 40 мкТл, а размах крыльев L=15м.
При движение проводника в М П возникает ЭДС индукции
е=U=B*V*L
800 км/с=800*1000/3600=222,22 м/с

U=40*10^-6*222,22*15=0,13 В

Ответ U=0,13 В

Calculation of Potential Difference between the Ends of the Wings of an Airplane

To calculate the potential difference between the ends of the wings of an airplane, we need to consider the horizontal velocity of the airplane, the vertical component of the Earth's magnetic field, and the wingspan of the airplane.

Given: - Horizontal velocity of the airplane: 800 km/h - Vertical component of the Earth's magnetic field: 40 μT (microtesla) - Wingspan of the airplane: 15 m

To calculate the potential difference, we can use the formula:

Potential Difference = Velocity x Magnetic Field x Wingspan

Let's plug in the given values and calculate the potential difference.

Velocity: The given velocity is 800 km/h. We need to convert it to m/s to match the units of the magnetic field and wingspan.

1 km/h = 0.2778 m/s

So, the velocity of the airplane is: 800 km/h x 0.2778 m/s = 222.24 m/s

Magnetic Field: The given vertical component of the Earth's magnetic field is 40 μT (microtesla). We need to convert it to tesla (T) to match the units of the velocity and wingspan.

1 μT = 10^-6 T

So, the magnetic field is: 40 μT x 10^-6 T/μT = 4 x 10^-5 T

Wingspan: The given wingspan of the airplane is 15 m.

Potential Difference: Now, we can calculate the potential difference using the formula:

Potential Difference = Velocity x Magnetic Field x Wingspan Potential Difference = 222.24 m/s x 4 x 10^-5 T x 15 m

Calculating the above expression gives us the potential difference between the ends of the wings of the airplane.

Please note that I couldn't find a specific source to cite for this calculation. However, the formula used is a standard formula in physics for calculating the potential difference in a magnetic field.
